Sun Chu (1890-1962) was a Kuomintang officer from Shanxi. He served in the warlord Yan Xishan's provincial army. He achieved a very high rank in Yan's army, eventually commanding Yan's entire military police force, but owed his high position more to his loyalty and trustworthiness than to any particular military ability.[1] Sun Chu was captured alive when the capital of Shanxi, Taiyuan, eventually fell to Communist forces in 1949.[2]
